Fauna of New Guinea
The island's isolation has caused strange birds and mammals to evolve. There are no apes or monkeys in the rainforests. With no large carnivorous mammals to compete against, birds and reptiles have flourished. There are over 700 species of birds. Just about the only mammals to arrive on the island, were those that could fly. New Guinea supports an amazing variety of bats and is the fruit bat capital of the world. The largest land predators are lizards, which have grown to gigantic proportions. There are 6 species of monitors alone, including the largest which is over 4 meters in length. The rainforests are home to tree kangaroos and birds like the enormous flightless Cassowary and the largest pigeon in the world. Thirty-eight species of birds of paradise attract mates with amazing dancing and their beautiful feathers.

The Bird of Paradise
The most famous avifauna (a fancy way of saying bird species!) in New Guinea is the bird of paradise. Of the 43 known species of birds of paradise, 38 are found in Papua New Guinea. These brilliantly colored birds do bizarre mating dances. The males are more colorful than the females. They were hunted by early traders for their feathers.
New Guinea is well-known for the beauty, size and variety of its insects especially its butterflies. The beautiful Birdwing butterflies are the largest in the world and only found in this region.

Insects have grown to be monsters, like the foot long stick insect. There are moths the size of dinner plates.

Reptiles
Monitor lizards
Varanus salvadori may grow to about the length of 15 feet from head to the tip of its tail; and is currently recognized as the longest lizard in the world. Like all other Monitor Lizards of the Varandae family, the Salvadori monitor can be distinguished by it's long thin forked tongue; the only other reptiles to share this common trait are snakes. It possess long sharp teeth, which enables it to easily hold its prey within its mouth while climbing up and down trees. Varanus salvadori also have 5 strongly clawed digits on its 4 appendages.Its smooth skin is sought after by natives of Papua New Guinea, for the skin of Kundu Drums. Its head and neck are long, and are both covered by overlapping polygonal shaped scales. The Salvadori monitor also has a particularly long and sturdy tail that may be aptly used in self-defense.
The skin of the Salvadori is predominately black covered with white specks or dots on its body. The most distinguishable aspect of the Salvadori monitor, apart from other members of the Varandae family; are its exceptionally long and sleek body.
